Direct Drive UnitsPennBarry’s Muffan replaces foul or contaminated air that is removed by a building’s exhaust system.

Such make-up air is so essential that it is part of safety and building code requirements for commercial kitchens, chemical laboratories, electrical control rooms and anywhere gas equipment is installed. Proper make-up air provisions should be part of every building plan.

Without adequate make-up air, air starvation can create negative pressures within a structure. Doors open with difficulty. Dirt, insects, and debris are drawn in through entrances. Fumes and odors accumulate. Pilot lights operate erratically. Moisture is sucked in through cracks in roofs and walls and around windows and doors. Air becomes stale. Backdrafts occur. Air handling systems operate ineffectively, inefficiently, and expensively. Heated or cooled air is wasted when make-up air is not properly considered.

On the other hand, uncontrolled airflow through windows and doors creates drafts, lets heat escape, and admits moisture, dust, dirt, and pollen.

The Muffan’s ability to regulate airflow ensures proper replacement air volume under varying conditions. The Muffan can be coordinated to match the exhaust velocity required to remove fumes, vapors, and grease while providing sufficient oxygen, thus feeding the system effectively.

Belt Drive UnitsLarger belt drive models extend the range of the Muffan. Now, clean air volumes approaching 14,000 CFM can be supplied to replace exhausted air and fumes.

Blowers are of an efficient, double inlet, forward-curved design in strong, die-formed steel housings. Variable pitch pulleys allow adjustment in RPM for more precise regulation of airflow. Motors, belts, pulleys and other components form a dependable, durable and quiet-operating assembly, easily balanced to meet system requirements.

MU ModelsThe housing’s louvered sides permit a direct air path, giving the housing a low profile to the roof. Cleanable, permanent filters back-up each louvered side to prevent airborne contaminants from entering. Filters are easily removed for cleaning.

An integral mounting base permits easy installation on a roof curb. Roof curbs speed, simplify, and coordinate installation of roof-mounted supply and exhaust equipment. PennBarry offers an extensive variety of curbs for mounting on flat and sloped roofs.

Speed (RPM) shown is nominal. Performance is based on actual speed of test. Other speeds listed are obtainable by using matching Lek-Trol™ speed controller. Performance shown is for installation type B - free inlet, ducted outlet. All static pressures shown are EXTERNAL. 0” S.P. INCLUDES all fan housing losses including the drop across CLEAN filters. Ratings include the effects of filters in the airstream.* Outlet Velocity = CFM / .75 Tip Speed = 1.9 x RPM.** Outlet Velocity = CFM / .66 Tip Speed = 2.1 x RPM.*** Outlet Velocity = CFM / .87 Tip Speed = 2.4 x RPM.
